The projects of reconstruction of the enterprise and construction of new facilities for expansion and modernization of production have been considered by the management of ANPZ for many years. When finally these plans became practical and the question arose about the candidacy of a general contractor for implementation, the choice fell on PROMFINSTROY JSC. By that time PROMFINSTROY was already an enterprise with a stable reputation as a serious and experienced partner in the field of industrial construction. For example, as part of the modernization project of the Orsk Plant, PROMFINSTROY JSC successfully carried out similar reconstruction and construction work.
Fruitful cooperation between ANPZ and PROMFINSTROY JSC was implemented in two stages. In 2012, PROMFINSTROY started a two-year project for the construction of a gallery railway draining and filling overpass and general factory facilities. In parallel, in the same years, the reconstruction of the ANPZ tank farm took place. All the facilities were commissioned on time — in 2014. Thanks to this, the Afipsky Oil Refinery was able to increase production in general, strengthen and expand the scope of its activities.
In 2019, the Afipsky Refinery started a production modernization program — the construction of a hydrocracking complex. The main objects of the complex are the hydrocracking plant itself and the factory facilities, as well as the hydrogen production plant and the sulfur production plant.
Construction and installation works on the construction of hydrocracking and hydrogen production plants were the first to start. At the end of 2019, PROMFINSTROY started a project for the construction of a sulfur production plant, and the construction of factory facilities began next year. In particular, since 2021, a new stage of the project has begun — the construction of local treatment facilities and inter-shop overpasses.
The prospects of commissioning a new hydrocracking complex and a delayed cracking unit give ANPZ new production capabilities for deep oil refining and for the production of marketable products. It is planned to increase the processing depth from 76.7% to 98.1%, and the output of light oil products — from 54.2% to 87.7%.
In addition, the Afipsky Oil Refinery, having increased its capacity, will exclude fuel oil and vacuum gas oil from the product line, using them as semi—finished products for further processing and production of light oil products - high-quality and in demand by the market.
In 2019, on November 1, a contract was signed for the construction of the facility "Hydrocracking Complex, Stage 1 (hydrocracking unit — tit. 3100, hydrogen production unit — tit. 4100, substation building with local hydrocracking equipment unit — tit. 3110, substation building with local hydrogen production equipment unit — tit.. 4110)"..
This hydrocracking complex is located in the south-east of the Afipsky Refinery production site and covers an area of 85358 m2. The total capacity of the complex for raw materials is 2.5 million tons per year when operating for 8,400 hours per year. The inter-repair mileage of the complex is 2 years. The estimated life of the complex is 20 years.
The hydrocracking complex is designed for processing raw materials (vacuum gas oil) into the following products:
To date, work is underway on the second stage of the construction of the complex (installation of sulfur production). The installation of monolithic reinforced concrete structures in the volume of 20604 m3 was completed; 12223 tons of metal structures were installed; since September 2021, the laying of a technological pipeline along interblock overpasses has begun, 111 units of technological equipment — both large-tonnage and prefabricated - have been installed. Since November 2022, PROMFINSTROY JSC has started assembling the sheet tank TK-7101 (3000 m3), and the foundation is also ready for assembling two more sheet tanks — TK-5101 (600 m3) and 5102 (200 m3)..
PROMFINSTROY JSC performed 85% of the work on the vertical layout of the site of the VOC facility (more than 70,000 m3 of soil was developed and transported to the embankment), mounted more than 790 tons of reinforcing rods, laid more than 20,000 m3 of concrete mixtures. The manufacture and supply of metal structures has begun — to date, more than 2,300 tons of metal structures have been delivered to construction.
Work is underway on all sections of the southern and northern overpasses of the MCC — on the development of soil, the driving of reinforced concrete piles, cutting off the heads of piles and the installation of reinforced concrete foundations. More than 15,000 m3 of soil has been developed. The company has started the installation of metal structures. To date, more than 1,400 tons of metal structures and more than 1,500 m of technological pipelines of the overpass have been installed. The foam sump unit is 98% complete. In 2022, two pieces of equipment were installed. In February 2023, it is planned to install four tanks with a volume of 50 to 100 m3.
More than 10 subcontractors are involved in the implementation of projects. More than 150 workers and specialists, as well as at least 16 units of construction equipment are on the construction site every day.
